Fantastic men and their mighty machines

Why we do what we do is a question only we can answer. Why some road test a desk making PowerPoint presentations all day while others punch the other extreme; pulling, pushing, dropping, dragging and uselessly spinning the back wheel of a bike that weighs double their own weight in the middle of the afternoon in a wildly remote corner of the Sahara, all while getting peppered by rocks and mud thrown up by another bikeahamr five meters ahead, doing the exact same pulling, pushing, dropping and spinning retinue. Why would you put yourself through that?
